Hi. I recently purchased a Sega 29Z21. I purchased it because it has very slight burn and its getting more and more difficult to get decent 29inch monitor these days. Anyhow, this was first time I faced this 29Z21 model and attached chasis has lack of pots compare to ms9-29.
Is it possible to swap with ms9-29 chasis? Would this be full compatible?

yes works perfectly, you need to make an adapter for the deflection yoke as the sanwa is 4 pin and the ms9 is 2 pin + 2 pin and the vertical header is a smaller gauge
the rgb and manual degauss connector are also different
